ANCHORING RETAINER FOR THREADED FASTENERS

摘要

645.005 An anchoring retainer is provided for mounting at one side of a supporting structure such as a wall, ceiling or the like having an opening therein. The retainer is used with a threaded element or fastener which extends from the other side of the supporting structure through the opening into the retainer and together forms a fastener assembly. The retainer comprises a flexible unitary one-piece plastic body having an axis which is adapted to extend through the opening in the supporting structure. The body has a generally triangular configuration and is provided with a sleeve at the apex of the triangle. An opening is provided in the sleeve surrounding the axis. The sleeve at the edges thereof located on opposite sides of the axis is provided with a pair of integrally formed outwardly diverging legs. A flexible control strut is spaced axially from the sleeve and has the ends thereof integrally connected to the outer end portions of the flexible legs. The control strut has a central aperture axially aligned with and spaced from the sleeve opening and through which the threaded element is adapted to extend. The control strut is moved away from the sleeve and towards the supporting structure to extend or expand the outer ends of the flexible legs to firmly grip the structure upon the threading of the threaded element or fastener into the opening in the sleeve.
